Abstract

A power tool includes a table. A shaft is fixedly secured to the table. The power tool also has a support housing supporting a motor and a working tool driven by the motor. The support housing is disposed on the shaft adjacent to the table and is axially movable along the shaft and laterally pivotable about an axis of rotation. In addition, the power tool has a locking mechanism for locking the support housing at a predetermined lateral position, wherein the locking mechanism includes a handle disposed on the shaft. The handle is rotatable in two directions with respect to the shaft, such that rotation of the handle on the shaft urges the support housing into locking contact with the table. A method for operating the power tool is also disclosed herein.

Claims9

Dependent claims

An apparatus for locking first and second components, said apparatus comprising:

a shaft disposed on the first component, said shaft having an axis and a first surface having a first thread disposed thereon in a first orientation, and a second surface having a second thread disposed thereon in a second orientation, said first and second thread intersect forming a V-shaped thread;
a handle disposed on said shaft, said handle being rotatable in two directions with respect to said first component, wherein the second component is disposed between the handle and the first component;
a protrusion disposed on one of the handle, and the first and second components, the protrusion contacting the first surface, such that, upon rotation of said handle in both directions neutral position, the second component is urged into contact with said first component.

Dependencies are inferred from the claim text.
